This rule checks to ensure that the used drill-pairs match the currently defined drill-pairs. The used drill-pairs are determined from the vias and pads found in the board. The permissable drill-pairs are defined in the Drill-Pair Manager dialog.

All design rules are created and managed within the PCB Rules and Constraints Editor dialog. For a high-level view of working with the design rules system, see Constraining the Design - Design Rules. For detailed information regarding how to target the objects that you want a design rule to apply to, see Scoping Design Rules.
